Application filed September The invention relates to an improvement in inner soles for shoes in which .the inner sole is provided at the heel portion with a shock-absorbing pad havinga shell backing of metal or other hard substancev and. a wrapping orjcovering of someflexible material passed over the upper surface of the pad and aroundthe adjacent marginal edges or the inner soleend fastened to the under side thereofl r V The object of the invention is to improve the pad, the shellend the cover both structurally and in point of operative efiiciency. n The invention can; bestgbe seen and understood. by reference to the drawings, .in
